Build Requirements for CentOS 7 Builds

Some CentOS builds require packages provided by EPEL or other external repo not available to OBS environment.
In order to make these packages available rebuild them here - from unaltered SRPMS - and use/include the resulting custom EPEL7 Repo in the main project.
USE ONLY TO RESOLVE CENTOS BUILD DEPENDENCIES IN OBS!
DO NOT INSTALL RPMS FROM HERE!
